Description

Preparation method for heating non-burning tobacco cigarettes

The present application claims priority to Chinese Patent Application No. 2016 1024 757 6.7, filed on Apr. 20, 2016, the entire disclosure of which is incorporated herein by reference. Combined in this application.

Technical field

The invention relates to the technical field of tobacco, and more particularly to a preparation method for heating non-burning tobacco cigarettes.

Background technique

Heating non-burning cigarettes provides consumers with nicotine and tobacco characteristics by heating non-burning tobacco to meet the needs of consumers, while greatly reducing the release of tar and harmful substances in mainstream smoke, which is the future development of the tobacco market. An important trend.

Because of the huge difference between the way they are used and traditional cigarettes, the design of heating non-burning cigarettes is inevitably different from traditional cigarettes. Related experiments have shown that ordinary cigarettes that have not been specially treated cannot be used in general smoking articles to provide satisfactory smoke and aroma.

Reconstituted tobacco is an important tobacco raw material. It has the following three benefits in heating and non-burning tobacco products: (1) It can be made into a sheet material, which can solve the phenomenon of tobacco shedding to a large extent; (2) a greater degree of guarantee The uniformity of the quality of tobacco products provides a more sensory and more consistent smoking experience; (3) the improvement and improvement of the heating of non-combusted tobacco products due to the fact that the chemical composition of tobacco can be changed to a greater extent as needed during the preparation of reconstituted tobacco leaves. The quality of the market has obvious advantages in meeting the individual needs of the market. However, the main purpose of remanufactured tobacco leaves is to improve the efficiency of tobacco raw materials and improve economic efficiency. The raw materials used are usually waste tobacco, tobacco leaves and stems. Therefore, most of the tobacco substrates in the whole lack the characteristic aroma of cigarettes. Insufficient, heavy gas and wood gas. At the same time, the reconstituted tobacco is mainly used after being shredded and added to the cigarette. Generally, the humectant used is low in content, and the high concentration of smoke cannot be provided in the use of the heated non-combusted tobacco product.

A method for preparing an electric dry-cut type tobacco sheet is provided in the patent document with the publication number CN 103181613. In this patent document, a tobacco extract, a plant extract and a smoke generating agent are coated on a tobacco sheet base, and are applied to an electric pyrolysis apparatus to generate smoke. However, this patent document simply modifies the ordinary sheet by means of sheet coating, and does not take into account the influence of the sheet on the cigarette smoke and the release of the tobacco aroma.
